cmake编译构建错误总结

1、make时发生类似以下错误：

error:stray ‘\342’ in program
           

代码中出现了中文字符，例如：“　”。

２、执行　make install 可能会出现以下错误：

CMake Error at lib/cmake_install.cmake:48 (file):
  file INSTALL cannot copy file
  "/cmake/t3/build/lib/libhello.so.1.2" to
  "/usr/lib/libhello.so.1.2".
           

解决办法：

make install 改为
sudo make install 并输入密码即可
           

３、注意：在cmake　…时可能会出现下列错误：

CMake Warning at src/CMakeLists.txt:1 (FIND_PACKAGE):
  By not providing "FindHELLO.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "HELLO", but
  CMake did not find one.

  Could not find a package configuration file provided by "HELLO" with any of
  the following names:

    HELLOConfig.cmake
    hello-config.cmake

  Add the installation prefix of "HELLO" to CMAKE_PREFIX_PATH or set
  "HELLO_DIR" to a directory containing one of the above files.  If "HELLO"
  provides a separate development package or SDK, be sure it has been
  installed.

           

解决办法：

将ADD_SUBDIRECTORY(src)放在
SET(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake)的后面
